Macroscopic findings. a The resected tumor was 5.2 × 4.0 × 3.1 cm in size. b The cut surface on gross examination was yellowish and elastic. c The tumor originated in submucosa. The narrow-dotted line showed smooth muscle (muscularis mucosae). The heavy-dotted line showed cross-striated muscle (tunica muscularis). The mucosal and muscular layers were thinned due to the local compressive effects of the tumor
